Beating a dead horse here, since it's been mentioned twice already, but
yeah --- $_SESSION's are the way to go with this.
<?
session_start();
$_SESSION['error'] = $error;
$_SESSION['parameter'] = $parameter;
header("Location:".$data[rurl]);
exit;
?>
And wherever you have your error handling, do:
<?
session_start(); // If not called from a header.php-like start file.
if($_SESSION['error']) {
// Do something with $_SESSION['error'] and $_SESSION['parameter']
}
?>
And for the record, it's not just the HTTP server that trims it, but the
browser generally does, as well, to avoid things such as memory leaks, et
cetera. Internet Exploder, for example, has had a limit of 2,083 total
characters in a GET request, but the actual RFC for HTTP/1.1 has no limit
for the protocol (RFC 2616 Section 3.2.1).
And slightly off-topic, but think about how much the web has changed in
the last 20 years (well, 17, since the HTTP protocol came about in 1990)....
and then think about the fact that it's all still based on nothing higher
than version 1.1.

This is a normal behaviour. Webservers trim the GET-request at a certain
length.
You have several options:
- don't do a redirect but return the form, with most clean frameworks it
should be no problem to include the action wich generates the form
- save the variables in a session, then send the redirect-header and
clean the session after regenerating the form
- save the variables in a cookie stored at the client and clean the
cookie afterwards (ugly)
